I'm going to get heretical here and say that I think modeless interaction is a flatout bizarre model for multitouch ... and that multitouch in existing kiosk applications (ATMS, Ticket kiosks, etc.) is a usability disaster waiting to happen.

Multitouch really shines in multiuser productivity apps and in situations where there is more content and data than can be analyzed

If you are going to design modeless interactions, why not go a step further and just do single point directed disclosure...like every ATM in christendom. That's the most usable touch interface framework.
